    Connect and test your Nintendo-style controllers

    Connect the controller to your computer with a supported USB or Bluetooth connection. Then press a button with this page focused. If no standard mapping appears, inspect raw axes and buttons in the advanced panel.

    1. Choose the intended controller from the device menu.
    2. Press each button and move both sticks.
    3. Run a resting-stick measurement if the browser provides a standard mapping.
    4. Save a snapshot with your connection and profile noted.

    Mapping and feature limits

    Nintendo-style face-button lettering differs from Xbox lettering. The label selector is visual only; game and remapping settings still determine the action. Digital trigger readings do not have a gradual analog range. Motion, NFC and console-specific haptics are not tested here.

    A browser-reported device name may describe a virtual device instead of the controller in your hands. Get connection and mapping help →
